1 Claim.

This invention relates to a device for passing oil through an observation tube and in proximity to other oils in corresponding tubes, whereby the oils in the diiierent tubes may be compared for obvious purposes.

A further object of the invention is to provide means for extracting oil that has been used in a bearing or otherwise in an engine and passing it through a glass tube in proximity to another glass tube containing non-used lubricating oil.

Another object of the invention is to so construct the casing to provide for an economically cast hole through the casing and to fasten the parts together to form an attractive casing.

Another object of the invention is the provision of label holders on the casing for properly identifying the oils observed and for advertising purposes.

Another object of the invention is to provide a casing for the extracting tube of the device whereby the extracting tube may be enclosed within the casing to prevent dripping of the oil while it is being observed.

With these and other objects of the invention which will be disclosed as the description proceeds, I will now describe my invention in connection with the attached drawing in which:-

Figure 1 is a view, partly in section, of my device, which, for lack of a better name, I denominate an oilscope.

Figure 2 shows a casing for the extracting tube ll of Figure 1.

Figure 3 is a sectional view of the casing proper, and

Figure 4 is a sectional view on the line -4 of Figure 3.

l is a frame which I conveniently make in two parts, llllil'. Each of the portions Iii-l in general outline are much the same shape. The portion it has a lower extension it through which a channel 18 is formed. The portion it has an upper extension and a channel I8 extending therethrough, as shown best in Figure 3. The upper portion of the part it has a cavity in which a pump casing 8 may be tightly fitted. This pump casing or cylinder may have an ordinary piston rod 6 and a double piston 99, snugly fitting in the casing 8 and with a handle 5 to operate the piston.

The other portion ll! may be conveniently screw threaded at its bottom extension to form a nipple and has on its lower extension a tube [5 attached to the portion It by attaching means l4. I6 is a coupling which holds the tube I: into alignment with the tube [5. The tuna; tion of the tube I1 is to allow connection between the device and an oil holding portion of an engine whereby lubricating oil may be withdrawn from a bearing or other portion of the engine through a tube H and the flexible portion I5 and on through the channel it.

The parts ltl0' of the frame have sockets, as shown in Figure 3, in which oil tubes may be seated. These oil tubes, numbered 29, 2|, Z2, 23, 24, 25, are devised for holding non-used oil. The tubes are fitted into their sockets so that the oil cannot escape and it is apparent from the construction shown in Figure 3 that when the pump piston is operated it will draw the used oil through the tube ll, flexible portion l5, channel l8, up to an oil tube 26, through the same and through the channel it. When the used oil is in the tube 26, it can be readily cornpared to the non-used oil in the other tubes 20, 2!, 22, 23, 2 3, 25, and the condition of the oil passing through the tube 26 may be ascertained by this comparison.

The portions It and it each have a projection H extending sideways and the projections each have a groove 4, as best shown in Figure 4, and a cap H. The object of these projections is to hold cards 52-52 in the groove 4 and retain them therein by the caps l I'| i. The object of these cardboard labels is to carry the name of the lubricating oil, the sales of which are being promoted.

The parts l l9, H) are conveniently held together by means of screws 2329, and by loosening these screws the parts lill0' may be separated for convenience in manufacture to receive the oil tubes and for convenience in making the channels i8-l8'.

2? represents a rigid cross-bar. There may be 3 or more which serve as a guard or protection to the glass tubes and may conveniently be fastened to end pieces 2'i'2'l which are held to the frame by screws 3il3fl.

The piston parts 9! may be ordinary leather or other substance crimped over at their edges and snugly sealing the piston in the pump.

It is apparent from the foregoing how the device is operated. The tube 2 normally encloses the tube i5, coupling it and the tube H, the tube 2 being screwed on to the screw threads at it. When it is desired to use the apparatus, the tube 2 may be removed and the tube l l inserted in the used lubricating oil. By drawing up on the pump handle 5, the oil will be drawn through the tubes lll5 and through the channel l8, thence through the tube 26 and the channel l8 to the pump cylinder 8. After the lubricating oil is pumped from the bearing or other part of the engine, the tube 2 may be used to cover the tubes I'I-l5 and when the tube 2 is screwed on to the screw threaded portion at M, it will prevent the dripping of oil after the device has been used in the suction of oil from the motor or other machine and while making comparison of used and non-used oil.

Having now described my invention, what I claim as new is:

A device of the character described, comprising a frame composed of two symmetrical and substantially L-shaped and complementary portions detachably connected together in rectangular formation, each portion including a base and an am so that when the portions are connected together the bases and the arms are respectively disposed in opposed relation, the arm of each portion having tube sockets provided therein and positioned in opposed relation when the portions are fitted together, a plurality of transparent tubes arranged transversely of the frame and parallel to each other and having their respective ends removably fitted in the sockets, each portion of the frame having a channel therethrough, a nipple integral with the base of each portion and communicating with the adjacent end of the channel in said portion, said nipples extending outwardly and in opposite directions relatively to each other, a. pump in communication with one nipple, an open ended flexible tube adapted to be inserted in an oil bearing and having the other end engaged with the other nipple, the transparent tube which is positioned in proximity to the base with which the flexible open ended tube communicates serving as a means for establishing communication between the other ends of the channels in the portions so that when the pump is operated the oil drawn therethrough will be completely Visible whereby instant comparison may be made between this oil and various grades of non-used oil adapted to be contained in the other tubes.
